Kafka + TLS/Kerberos in Cluster Streaming Mode is here!
Spark Streaming + Data Collector + Secure Kafka
When we first introduced cluster streaming mode with Apache Spark Streaming 1.3 and Apache Kafka 0.8 several years ago, Kafka didn’t support security features such as TLS (transport encryption, authentication) and Kerberos (authentication). In Spark 2.1, an updated Kafka connector was introduced with support for these features when used with Kafka 0.10 or newer.
